From Summer Storms to Winter Ready: Essential Commercial Roof Preparation
Fall is here, and if you’re a commercial property owner or facility manager, now is the critical window to assess summer storm damage and prepare your roof for the harsh winter months ahead. The transition from summer to winter is one of the most important times for commercial roof maintenance, yet it’s often overlooked until it’s too late.

Why This Timing Matters
Summer storms can be brutal on commercial roofing systems. High winds, heavy rains, and hail leave behind damage that might not be immediately visible but can become catastrophic when winter weather arrives. Small cracks expand when water freezes, minor leaks turn into major structural issues, and clogged drainage systems can lead to ice dams and roof collapse under heavy snow loads. The good news? October gives you the perfect opportunity to address these issues before the first freeze.
Step 1: Assess and Repair Summer Storm Damage
Summer weather takes a serious toll on commercial roofs. Start by conducting a thorough inspection of your entire roofing system, looking for these common storm-related issues:
- Wind Damage: Strong summer winds can lift shingles, tear membrane seams, and even peel back entire sections of roofing material. Check the perimeter and corners of your roof first, as these areas are most vulnerable to wind uplift. Look for any loose or missing materials, damaged flashing, and compromised fasteners.
- Hail Impact: Even if you didn’t notice hail damage immediately after a storm, it’s there. Hail creates bruising on membrane roofs, cracks in shingles, and dents in metal components. These compromised areas become entry points for water, which will freeze and expand during winter, causing exponentially more damage.
- Water Intrusion: Summer thunderstorms are intense and can expose weaknesses in your roofing system. Check your ceiling tiles, insulation, and interior walls for water stains or discoloration. These are telltale signs of leaks that need immediate attention before winter precipitation makes them worse.
- Ponding Water: After summer rains, walk your roof and identify any areas where water pools and doesn’t drain within 48 hours. Ponding water accelerates roof deterioration and becomes a serious problem in winter when that standing water freezes, adding tremendous weight and stress to your roof structure.
Don’t wait to address these issues. What seems like minor damage now will multiply when exposed to freeze-thaw cycles throughout the winter.
Step 2: Clean Your Gutters and Drainage Systems
This might be the most overlooked aspect of commercial roof maintenance, but it’s absolutely critical. Your gutters and drainage systems are your roof’s first line of defense against water damage and winter ice buildup.
- Why Clean Gutters Matter: During summer and early fall, gutters collect leaves, twigs, dirt, and debris. When this material blocks your drainage system, water has nowhere to go. In winter, that trapped water freezes, creating ice dams that force water under your roofing materials and into your building. The weight of ice-filled gutters can also cause them to pull away from the structure entirely.
- What to Clean:
- Remove all leaves, branches, and debris from gutters and downspouts
- Clear all roof drains, scuppers, and overflow drains
- Flush the entire system with water to ensure proper flow
- Check that downspouts direct water away from your building foundation
- Remove any vegetation growing in gutters or on the roof surface
- Inspect While You Clean: As you’re cleaning, look for signs of gutter damage including rust, holes, sagging sections, and loose fasteners. Check that all gutter seams are sealed properly. Winter weather is unforgiving to compromised drainage systems, so repair or replace damaged sections now.
For multi-story buildings or complex roof systems, professional gutter cleaning isn’t just recommended, it’s essential for safety and thoroughness. Cole Roofing’s experienced team can handle the complexity of any commercial roof system.
Step 3: Prepare Your Roof for Winter
With storm damage repaired and drainage systems clear, it’s time to winterize your commercial roof. These proactive steps can save you from emergency repairs and business interruptions during the coldest months.
- Seal and Protect Vulnerable Areas: Pay special attention to roof penetrations, flashing around HVAC units, skylights, and vent pipes. These are the most common failure points during winter. Apply sealant to any gaps or cracks, and ensure all flashing is secure and properly sealed.
- Trim Overhanging Trees: Those branches that provide shade in summer become hazards in winter. Heavy snow and ice can snap branches onto your roof, causing immediate damage. Trim any branches hanging within six feet of your roof surface.
- Insulation and Ventilation Check: Proper insulation and ventilation prevent ice dams by keeping your roof surface at a consistent temperature. Check that insulation is dry and properly installed, and verify that all vents are clear and functioning. Poor ventilation allows warm air to escape through your roof, melting snow that refreezes at the eaves and creates destructive ice dams.
- Emergency Preparedness: Have a plan in place for winter roof emergencies. Know who to call for emergency repairs, keep contact information readily available, and establish a relationship with Cole Roofing before you need one urgently. Emergency repairs in winter are more expensive and difficult than preventive maintenance in fall.
- Schedule Professional Inspection: While property managers can spot obvious issues, a professional roofing contractor has the expertise and equipment to identify problems you might miss. Thermal imaging can detect moisture intrusion, and experienced roofers know exactly where to look for potential failure points. A professional inspection by the experts at Cole Roofing now can prevent tens of thousands of dollars in emergency repairs later.
The Cost of Waiting
Many commercial property owners delay roof maintenance, thinking they’ll “get to it later” or wait until there’s an obvious problem. This approach is costly. Emergency roof repairs in winter can cost three to five times more than preventive maintenance in fall. Factor in potential business interruption, inventory damage, and the difficulty of working in freezing conditions, and the true cost of waiting becomes clear. Consider this scenario: A small leak from unnoticed summer storm damage goes unaddressed. In December, water seeps in, freezes, and expands the crack. Snow accumulates on the roof. The leak worsens. Soon you’re dealing with water damage to inventory, potential mold growth, structural concerns, and the need for emergency repairs during the busiest season of the year. All of this could have been prevented with a few hours of inspection and maintenance in October.
